ABSTRACT:
A vacuum pump that includes an electric motor and a pump module mounted to the motor housing with the motor shaft being rotatably coupled to a pumping mechanism within the pump module. A pump inlet and a pump outlet are respectively coupled to the pumping mechanism within the pump module for pumping air from the inlet to the outlet upon operation of the motor. An inlet valve is carried by the pump, and is selectively movable by an operator between an open position in which the pump inlet port is coupled to the pumping mechanism and a closed position in which the inlet port is isolated from the pumping mechanism. In this way, the pumping mechanism may be connected to a system under service by placing the inlet valve in the open position to evacuate the system, and may be isolated from the system under service without disconnection therefrom by placement of the inlet valve in the closed position during service on or charging of the system.
